speed).

NOTE:
• Blows at no load per minute becomes smaller than
those on load in order to reduce vibration under no
load, but this does not show trouble. Once
operation starts with a bit against concrete, blows
per minute increase and get to the numbers as
shown in the table. When temperature is low and
there is less fluidity in grease, the tool may not
have this function even with the motor rotating.
CAUTION:
• The speed adjusting dial can be turned only as far
as 5 and back to 1. Do not force it past 5 or 1, or
the speed adjusting function may no longer work.

tool is switched on, the carbon brushes may be worn out,
or the controller, the motor or the ON/OFF switch may be
malfunction.
The red service indicator lamp flickers up when the

tool needs servicing. After approx. 8 hours of use, the
motor will automatically be shut off.
